Abstract
The utility model discloses an LED street lamp combination type phase change heat dissipation device, and relates to an LED street lamp heat dissipation device. The LED street lamp combination type phase change heat dissipation device comprises a main thermal conduction body. An LED light-emitting chip is connected to the bottom face of the main thermal conduction body. A closed steam thermal conduction cavity is formed in the bottom of the main thermal conduction body. Cooling fins which are fixedly connected with the steam thermal conduction cavity are arranged on the top of the steam thermal conduction cavity. A heat dissipation unit is arranged in the steam thermal conduction cavity and comprises foam metal and a heat dissipation block. The heat dissipation block is fixedly arranged on the top face of the steam thermal conduction cavity. The foam metal is fixedly arranged on the bottom face of the steam thermal conduction cavity. The portion between the heat dissipation block and the foam metal is filled with heat dissipation liquid. A thermal conduction pipe is fixedly arranged on the LED light-emitting chip and extends into the steam thermal conduction cavity to be connected with the foam metal. The LED street lamp combination type phase change heat dissipation device mainly has the advantage that heat on an LED light source can be rapidly transferred to the cooling fins and rapidly dissipated into air through the foam metal, the heat dissipation liquid and the heat dissipation block in the steam thermal conduction cavity.

Accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of LED street lamp combined type phase-change heat sink of the present utility model;
Wherein, 1, leading hot body; 11, steam thermal conductive cavity; 12, radiating block; 13, foam metal; 14, heat pipe; 2, left fin; 3, right fin; 4, LED luminescence chip.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearer, understand the utility model technical thought required for protection.
Be illustrated in figure 1 a kind of LED street lamp combined type phase-change heat sink of the present utility model, it comprises LED luminescence chip 4, leading hot body 1, left fin 2 and right fin 3.Leading hot body 1 both sides are connected with respectively left fin 2 and right fin 3, on the bottom surface of leading hot body 1, are connected with LED luminescence chip 4.The bottom of leading hot body 1 is provided with airtight steam thermal conductive cavity 11, and the top of this steam thermal conductive cavity 11 is provided with the fin being fixedly connected with it.In steam thermal conductive cavity 11, be provided with heat-sink unit, this heat-sink unit comprises foam metal 13 and radiating block 12, radiating block 12 is fixedly installed on the end face of steam thermal conductive cavity 11, and foam metal 13 is fixedly installed on the bottom surface of steam thermal conductive cavity 11, between radiating block 12 and foam metal 13, is filled with cooling fluid.On LED luminescence chip 4, be fixedly installed heat pipe 14, and this heat pipe 14 extends to, and steam thermal conductive cavity 11 is interior to be connected with described foam metal 13.
The quantity of steam thermal conductive cavity 11 is more than three or three.
The bottom surface of leading hot body 1 is provided with three airtight steam thermal conductive cavities 11 side by side, and it is to consider volume and the comfort level used in everyday of radiator that the quantity of steam thermal conductive cavity is set to the main cause of three.
